To all whom it may concern Be it known that we, HERMAN F; Benn. of Bronxville, in the county of Westchester and State of New York, and HAL fi ter- FORD, of Plainfield, in the county of'Union Jersey, have jointly in vented a certain new and useful Improvement in Locomotive-Engines, ofiwhicli improvement the following is a specification.

Our invention relates to locomotive engines for heavy of the class in which two groups or sets'of coupled driving wheels are rotated by separate and independent pairs of steam' c ylinders, and its object is to provide a locomotive of such class, in which the maximum haulin capacity derivable from the operation of two pairs of cylinders may be exerted with the restriction, to the minimum lengt of the rigid wheel base, maintenance of invariable lateral relation of the boiler to the frame and. cylinders, with the consequent elimination of joints in steam conveying pipes.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure l is a diagrammatic side view. in elevation. of a locomotive engine illustrathu: an cmlmdiment of our invention; Fig. 2, a vertical transverse section, the right hand half taken on the line a (I- of Fig. 1. and the left hand half, slightly in advance of said line; Fig. 3, a similar section, the right hand half taken on the line I) b of Fig. l, and the left hand half, slightly in rear of said line: I? in. fl, a view similar to Fig. '1, except in showing a different disposition of cylinders; and, Fig. 5, a diagrammatic side view of the wheels and cylinders, illustrating; a. struc tural modification in the manner of coupling the driving wheels.

In the practice of our invention, referring descriptively to the specific embodiment thereof which is exemplified in Figsv 1, 2 and 3, we provide a rigid frame, 1, comprising two side frame meml'iers of the ordinary construction, connector hy snitalole cross ties in the usual manner. he hoiler, 2, is secured at its front end to, and supported on, a pair of front cylinder sad- (lles, 3, each of \vhirh is cast integral with one of av pair of front stcam cylinders, 3.

and is firmly secured to the adjacent side,

The rear end of the boiler supported on the frame in any suitable and conven ent man.- ner, and is preferably connecte by the usual expansion plates or shoes, to provide for longitudinal expansion and contraction of the boiler, under variations of temperature, without movement, relatively to the frame. of rear steam cylinders, 41:, is secured to the frame, adjacent to the rear end of the boiler,

through half connecting members, l, cast integral with the cylinders and secured one to the other centrally, and to the side members of the frame.

A plurality of pairs of driving wheels, 5, secured upon axles, 5", 5, is interposed between the front and axles of all of said pairs of wheels, except the front and rear pairs, being; jonrnaled in driving boxes mounted in pedestals on the side frame members, in the ordinary man-- ner. Without being: limited to any specific miles and. wheels, the number thereof is determined by the maximum rigid wheel lease which is permissible under the conditions of operation for which the locomotive is designed. and the driving axles are disposed as closely togethcras the diameter of the wheel flanges will permit. The front driving axle. 5". and the rear driving axle, 5, are mounted in lateral motion driving horses, 6, which afford said axles a determined degree of lateral movemcnt. relatively to the frame members, to facilitate the traverse of the locomotive to, through. and track. and the determiiuul rigid wheel base of the hicomotive is thereby reduced minimum, and constituted by the longitudinal distancehetwecu the axis of the driv ing axle next succeeding the front one, 5 and that next preceding; the rear one, The lateral motion appliances of said front and rear driving axles, do not, inand of themselves, form part of our present inven tion and they are not therefore in detail herein forth. ln the instance exemplifled, they in Letters l'at'u it of the United States No. illSliEil. gran and issued to William ll Woodard and flamuel El. hiegel', under date of lllay 2-. i916, but any other means of providing the capacity of lateral motion in rear cylinders, the
